Southwest Airlines is waiving fees for passengers who want to avoid flying on the Boeing 737 Max 8 aircraft.

Southwest said, "We are working with customers who wish to rebook their flight to another aircraft type on a case-by-case basis." A Southwest rep said, "As a courtesy, we will waive the fare difference for the new flight between the same city pairs." The move follows an Ethiopian Airlines crash that killed all 157 people onboard, says Business Insider.
